Not that you would ever do such a thing, but don't mix MAIN and NOMAIN type
calls together in a program with F-specs.

That is, don't try calling the program via *ENTRY PLIST and then later
calling individual procedures within that same program via EXTPROC
prototypes.  I thought this would be a nice way to wean programs from CALLB
to CALLP, but it's actually quite ugly.  Evidently the "open" bit in the
F-spec is handled differently for the MAIN procedure than in subprocedures.

As I said, nobody would normally do this, but I thought it was a pretty
slick technique to migrate from old code to new code.  I could have old
programs doing CALLB until I converted all of them, at which point I'd just
remove the MAIN procedure.  Pretty slick.  Until I tried it.

Ya hey dere.
